Over at Many2Many, Clay Shirky points us to 10 Open Source Tools for eActivism, from the Democracy Online Newswire. The essay, written by Dan Bashaw and Mike Gifford, details a variety of programs for collaboration and communication available to people trying to make a difference in the world. They range from tools for online publishing, newsletter and mailing list management, discussion forums, even tools for quickly distributing posters. (Warning: as of the time of this posting, the links in the essay to the various tools seem to have a garbage character at the end of the URL; if you try to hit the links on the page and get an error, try deleting the "%20" at the end of the address.)
Free collaborative/creative tools and the activist community have a natural connection. Such applications are mechanisms for spreading news and ideas which, by their nature, also spread the ability to disseminate news and ideas to an ever-larger audience. To mangle an ancient metaphor, they are the software equivalent of giving a person a fish that, when eaten, teaches that person how to fish and where to find a fishing pole.
UPDATE: Jon Stahl's Journal links to this post, and adds some useful comments based on Jon's own experiences with some of the software mentioned in the article. He also suggests a few other useful tools, in particular a couple of non-Free but still useful membership and relationship management applications. Go read what he has to say.
Heh, I just chose Drupal for eAsylum.net... Though I would classify it more as a CMS than a Blog.
